Well, two other options would be to simply duplicate the device tree
files. I know that's a pain...

The other option is choose one or the other(arm64 vs. arm32), I would
guess pick arm32.  It works...  And at this time, arm64 doesn't have a
whole bunch of benefit on the RPI 3.  Perhaps maybe a RPI 4 will come
out someday and we will see more of a gain.
